Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline to Week 12 in Bladder Wall Thickness	Bladder wall thickness (BWT) measurements were obtained using transvaginal ultrasound. The BWT was derived as one mean value per image pooled over measurements of 3 locations (anterior wall, dome and trigone), and performed by 2 central readers and 1 adjudicator.	Baseline and Week 12
Primary	Neutralized Urinary Nerve Growth Factor Normalized by Urine Creatinine at Week 12	Free (neutralized) urinary nerve growth factor (uNGF) and creatinine (Cr) were measured from urine samples by the central laboratories.

Baseline, Week 6 and Week 12
Secondary	Change From Baseline to Week 6 and Week 12 in Neutralized Urinary Nerve Growth Factor Normalized by Urine Creatinine	Free (neutralized) urinary nerve growth factor (uNGF) and creatinine (Cr) were measured from urine samples by the central laboratories. Free (neutralized) uNGF/Cr was derived by dividing free (neutralized) uNGF concentrations [pg/mL] by the urine creatinine concentrations (µmol/mL) from the same participant.	Baseline, Week 6 and Week 12
Secondary	Change From Baseline to Week 12 in Mean Number of Events (Micturitions Plus Incontinence Episodes) Per 24 Hours	The average number of micturitions (urinations) and incontinence episodes (any involuntary leakage of urine) per day was derived from the number of events recorded by the participant in an electronic diary for 3 days before the Baseline and Week 12 clinic visits.	Baseline and Week 12
Secondary	Change From Baseline to Week 12 in Mean Number of Urgency Events Per 24 Hours	The intensity of urgency of each micturition (urination) and incontinence episode (any involuntary leakage of urine) was recorded by the participant in an electronic diary according to the Patient Perception of Intensity of Urgency Scale (PPIUS) as follows: 0 = No urgency; 1 = Mild urgency; 2 = Moderate urgency, could postpone voiding a short while; 3 = Severe urgency, could not postpone voiding; 4 = Urge incontinence, leaked before arriving to the toilet.; An urgency event is defined as any micturition or incontinence episode classified by the participant as a grade 3 or 4 on the PPIUS scale. The average number of urgency events per day is derived from the diary data completed by participants on the 3 days prior to the Baseline and Week 12 visits.	12 weeks
Secondary	Change From Baseline to Week 12 in Mean Number of Micturitions Per 24 Hours	The average number of micturitions (urinations) per 24 hours was derived from the number of micturitions recorded by the participant in an electronic diary for 3 days before the Baseline and Week 12 clinic visits.	Baseline and Week 12
Secondary	Change From Baseline to Week 12 in Mean Number of Urgency Micturitions Per 24 Hours	An urgency micturition is defined as any micturition classified by the participant as a grade 3 or 4 on the Patient Perception of Intensity of Urgency Scale (PPIUS) as follows: 0 = No urgency; 1 = Mild urgency; 2 = Moderate urgency, could postpone voiding a short while; 3 = Severe urgency, could not postpone voiding; 4 = Urge incontinence, leaked before arriving to the toilet.; The average number of urgency micturitions per 24 hours was derived from the number of urgency micturitions recorded by the participant in an electronic diary for 3 days before the Baseline and Week 12 clinic visits.

Baseline and Week 12
Secondary	Change From Baseline in Mean Number of Urgency Incontinence Episodes With PPIUS Grade 4 Per 24 Hours	An urgency incontinence episode is defined as any incontinence episode classified by the participant as a grade 4 on the Patient Perception of Intensity of Urgency Scale (PPIUS) as follows: 0 = No urgency; 1 = Mild urgency; 2 = Moderate urgency, could postpone voiding a short while; 3 = Severe urgency, could not postpone voiding; 4 = Urge incontinence, leaked before arriving to the toilet.; The average number of grade 4 urgency incontinence episodes per 24 hours was calculated from the number of urgency incontinence episodes recorded by the participant in an electronic diary for 3 days before the Baseline and Week 12 clinic visits.	Baseline and Week 12
Secondary	Change From Baseline to Week 12 in Mean Level of Urgency	The intensity of urgency of each micturition (urination) and incontinence episode (any involuntary leakage of urine) was recorded by the participant in an electronic diary according to the Patient Perception of Intensity of Urgency Scale (PPIUS) as follows: 0 = No urgency; 1 = Mild urgency; 2 = Moderate urgency, could postpone voiding a short while; 3 = Severe urgency, could not postpone voiding; 4 = Urge incontinence, leaked before arriving to the toilet.; The mean level of urgency was calculated by adding the PPIUS grade for all events (micturition or incontinence) and dividing by the number of episodes recorded in the diary over 3 days prior to the Baseline and Week 12 visits.	Baseline and Week 12
Secondary	Change From Baseline to Week 12 in Total Urgency Score	The intensity of urgency of each micturition (urination) and incontinence episode (any involuntary leakage of urine) was recorded by the participant in an electronic diary according to the Patient Perception of Intensity of Urgency Scale (PPIUS) as follows: 0 = No urgency; 1 = Mild urgency; 2 = Moderate urgency, could postpone voiding a short while; 3 = Severe urgency, could not postpone voiding; 4 = Urge incontinence, leaked before arriving to the toilet.; The total urgency score was calculated by adding all PPIUS scores over a 3-day period prior to the Baseline and Week 12 visits for each participant.	Baseline and Week 12
Secondary	Change From Baseline in Patient Perception of Bladder Condition (PPBC)	The PPBC scale is a global assessment tool that asks patients to rate their impression of their current bladder condition on a 6-point scale from 1: 'Does not cause me any problems at all'; 2: 'Causes me some very minor problems'; 3: 'Causes me some minor problems'; 4: 'Causes me (some) moderate problems'; 5: 'Causes me severe problems' and 6: 'Causes me many severe problems'. A negative change from Baseline score indicates improvement.	Baseline and Week 12
Secondary	Change From Baseline in Patient Assessment of Urgency Bother	The participants' perception and impression of bother associated with their condition were assessed using the Urgency Bother-Visual Analog Scale (UB-VAS). The participant was asked to place a vertical mark on a 100 mm line to indicate how much bother has urgency been for them in the past week, whereby 'no bother at all' is represented on the left end (score = 0) and 'worst possible bother' (score = 100) at the right end of the line.; A negative change from Baseline indicates improvement.	Baseline and Week 12
Secondary	Change From Baseline in Patient Assessment of Treatment Satisfaction	The treatment satisfaction visual analog scale (TS_VAS) asks patients to rate their satisfaction with treatment by placing a vertical mark on a 100 mm line where the endpoints are labeled 'No, not at all' on the left (score = 0) to 'Yes, completely satisfied' on the right (score = 100). A positive change from Baseline indicates improvement.	Baseline and Week 12
Secondary	Percentage of Participants With Improvement and Worsening on the 5 Dimensions of the EQ-5D	The participants' quality of life was assessed using the EuroQoL 5 Dimension Questionnaire (EQ-5D). The EQ-5D is a standardized instrument for use as a measure of health outcome and is based on the following 5 domains: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression. For each dimension participants were asked to select the statement which best described their health that day, from level 1 (indicating no problems) to 3 (indicating extreme problems/unable to perform).; Improvement was defined as a change from a state of being unable to perform or extreme problems at Baseline to no problems or to some or moderate problems at Week 12, and from some or moderate problems to no problems.; Worsening was defined as a change from no problems at Baseline to some or moderate problems or to a state of being unable to perform or extreme problems at Week 12, and from some or moderate problems to a state of being unable to perform or extreme problems.	Baseline and Week 12
Secondary	Change From Baseline in EuroQoL 5-Dimension Questionnaire Visual Analog Scale	The participants' quality of life was assessed using the EuroQoL 5 Dimension Questionnaire (EQ-5D) visual analog scale (VAS).; Health status is completed by the participant indicating their own health state today by drawing a line on a vertical scale from 0 to 100 where the endpoints are labeled 'Worst imaginable health state' (=0) and 'Best imaginable health state' (=100). On the EQ-5D VAS, a positive change from Baseline indicates improvement.	Baseline and Week 12
Secondary	Change From Baseline in Symptom Bother Score	Overactive bladder symptoms were assessed using the symptom bother scale of the Overactive Bladder Symptom and Health-Related Quality of Life Questionnaire (OAB-q). The OAB-q is a patient-administered instrument comprising an 8-item symptom bother scale and 25 health-related quality of life items (see next outcome measure). In the symptom bother scale participants were asked how much they had been bothered by selected bladder symptoms during the past 4 weeks. Each question has a 6-point Likert scale response ranging from 'not at all' (1) to 'a very great deal' (6).; The total symptom bother score was calculated from the 8 answers and then transformed to range from 0 to 100, with 100 indicating worst severity. A negative change from Baseline in symptom bother score indicates improvement.	Baseline and Week 12
Secondary	Change From Baseline in Health-Related Quality of Life (HRQL)	Health-related quality of life was assessed by the Overactive Bladder Symptom and Health-Related Quality of Life Questionnaire (OAB-q). The OAB-q is a patient-administered instrument comprising of an 8-item symptom bother scale (see previous outcome measure) and 25 HRQL items comprising 4 subscales (concern, coping, social interaction and sleep) and a total HRQL score. Participants were asked how their overall bladder symptoms had affected their life in the past 4 weeks. Each of the 25 HRQL questions has a 6-point Likert scale response ranging from 'none of the time' (1) to 'all of the time' (6).; The HRQL subscale scores were calculated by summing the responses of the items within each subscale.The HRQL total score was calculated by adding the 4 HRQL subscale scores,. All scores were transformed to a scale from 0 to 100 where higher scores indicate better quality of life. A positive change from Baseline in HRQL score indicates improvement.	Baseline and Week 12
Secondary	Change From Baseline to Week 12 in Brain Derived Neurotrophic Factor Normalized by Urine Creatinine (uBDNF/Cr)	Brain derived neurotrophic factor (uBDNF) and creatinine (Cr) were measured from urine samples by the central laboratories. uBDNF/Cr was derived by dividing uBDNF concentrations [pg/mL] by the urine creatinine concentrations (µmol/mL) from the same participant.	Baseline and Week 12
Secondary	Change From Baseline to Week 12 in Total Urinary Nerve Growth Factor Normalized by Urine Creatinine	Total (acidified) urinary nerve growth factor (uNGF) and creatinine (Cr) were measured from urine samples by the central laboratories. Total uNGF/Cr was derived by dividing total uNGF concentrations [pg/mL] by the urine creatinine concentrations (µmol/mL) from the same participant.	Baseline and Week 12
Secondary	Percentage of Participants With Improvement or Deterioration in Patient Perception of Bladder Condition (PPBC)	The PPBC scale is a global assessment tool that asks patients to rate their impression of their current bladder condition on a 6-point scale from 1: 'Does not cause me any problems at all'; 2: 'Causes me some very minor problems'; 3: 'Causes me some minor problems'; 4: 'Causes me (some) moderate problems'; 5: 'Causes me severe problems' and 6: 'Causes me many severe problems'.; Improvement: = 1 point improvement compared to Baseline; Major Improvement: = 2 point improvement compared to Baseline; Deterioration: = 1 point deterioration compared to Baseline.
